Castle Mamba Monster 2 Drivers Ed Guide
High Power
Brushed Motor Mode:
Using High Power Brushed Motor Mode will allow for the use of lower turn
count brushed motors, and forward only operation. Make sure you change
the Motor type setting to “Brushed High Power” in the ESC before using a
brushed motor. Connect all three of the ESC motor wires to the negative (-)
side of the motor. You can either use a “Y” harness from the ESC battery
input positive wire to connect to both the battery and the positive side of
the motor, or use a single wire from the positive ESC input to the positive
battery pole and then continue to the positive (+) side of the motor.
RADIO CONNECTION
Your Castle ESC plugs into the throttle channel of your receiver. This is
usually channel 2. Your Castle ESC provides 5 – 8 volts to the receiver to
power the receiver and the steering servo. No separate receiver battery
is needed to power the radio system. Some servos can draw more current than the onboard BEC can handle and will require an
external BEC or receiver pack.
Castle ESC receiver plugs are made to be used with any current receiver, but you will need to make sure the polarity is correct when
plugging into the receiver. The signal wire is orange, the positive wire is red, and the negative is brown. Some radio systems use
white for signal, red for positive and black for negative color scheme. Check your receiver documentation for correct connection
polarity if it’s not marked.
Note: most receivers use negative to the outside of the case and signal towards the inside of the case.
ESC SETUP
ESC/Radio Calibration
Individual transmitter’s signals for neutral, full throttle, and full brake vary. You must calibrate your Castle ESC so that it will
operate eectively with your transmitter. Anytime the ESC is powered up with a new transmitter, or with dierent throttle channel
settings, it will need to be calibrated to “know” what the transmitter’s throttle settings are. It will also need to be calibrated after
updating with new software via Castle Link.
If you are using a Futaba or Futaba OEM brand transmitter, you will need to set the transmitter’s throttle channel direction to
the REVERSE (Rev) position. This is either an external micro switch on the transmitter or an option available within the computer
programming of the transmitter.
Please start by zeroing out any throttle trim that you may have set in your transmitter.
Don’t plug in the battery yet! Make sure that the battery polarity and input polarity on the ESC are correct. Check the
on/o switch of the Castle ESC to make sure that it is in the OFF position. We recommend removing your pinion gear
before calibration as a safety precaution!
How to Calibrate the ESC
Step 1: Start with the transmitter ON, the battery disconnected, and the ESC’s switch in the OFF position (if ESC has a switch).
Step 2: Plug a battery into your Castle ESC. (NOTE: If your ESC does not have a switch, hold full throttle on your transmitter before
plugging in the battery.)
Step 3: Hold full throttle on the transmitter and turn the ESC’s switch ON. Keep holding full throttle on the transmitter. If all your
connections are correct, you will hear one multi-toned initialization “ring” from the motor (all tones are played by the ESC vibrating
the motor).
STEP 4: After a second or two, the green LED on the ESC will blink rapidly and the motor will “ring” 4 times rapidly in a row
(accepting the full throttle endpoint). After the green LED flashes and tones, the ESC will blink the red LED. At this point the full
throttle endpoint has been set within the ESC and now it’s looking for the full brake endpoint (red LED blinking).
STEP 5: Move the throttle trigger to the full brake position and hold full brake. After a few seconds, the ESC will flash the red LED
and ring 4 times rapidly (accepting full brake endpoint).
STEP 6: After accepting the full brake endpoint the ESC will then blink the yellow LED. Now relax the trigger to the neutral
position. The ESC will now ring 4 times and flash the yellow LED rapidly to accept the neutral position.
After accepting the neutral position, the ESC will ring twice, flash ALL the LEDs, and the yellow LED will illuminate (solid yellow
for all ESCs except Mamba Max Pro which flashes). This is the arming tone and LED indication that the ESC IS NOW ARMED and the
car will respond to throttle inputs from your transmitter.
